SPARK FLUG Filed Aug.

f'] TTORNE Y When a lzproggwexn ceut to *abe Spuk ping; s closed, the spaces between the meta #xezs 18 and 19 on the two pari; eeotoe :m the rings 22 at 51st prevent the pressage of the eu'ent to the temnal points; FZ7, but when a sucen; emmen?, has aocumue'e; ol oondense in the conductor in the Various eonneotionsan. in the meemy iu be tube 33 in e menne? We calmo@ exp'en, ile@ spark jumps @arose from the disk l@ io the disk 197 using he wings 22 .3 szeps in its Wbb. The roem?, is a streng demi spark between one o; more of the Spazvk ponts'( and he lower en@ of the bushing l, In practice, spmys from a Bombes: of these spark pointe 2'? emutvneousy when vthe distance between them une the bushing is the Seme.

We pefe to use the disks 18 and l and the rings E22 to the. useo' a. pair of spark points as the latter are hable to bum :may in, time and adjuetment is substantaly impossible, While the disks and finge .la-Si: indentely.

Tm. Figs. 4 to 7 We have shown a sees of other electrode teminals which embody the same iee of a. series of spak points. 1n IGf. is shown a plain disk 35, Screwed onto the lower end of the p-a't; 2l o the centred eleotrode The points 36 are, mounted in the lower end. of the bushing l and the purpose and effect of this constellation is the same as above described.

In Figa 5 and-6 We have shown a terminal ring 38 connected to he lower end of the bushing 1 by means o pine 39, which may be of any desired length to carry the lspark gap into the combustion chamber.

The te'mina disk 40, screwed onto the ee'etrede 2, has radial points 4l While the inner suda/ce of the ring 38 is 'russownoel an. ute.

Ih Fig. 7 the lower end of the bushing 1 is bev'eed inwary so as to be substantaly paare-Hel to the ends of the teeth 43 on the ring 44. of the te'mxml which also embodies a spider 45 W'oh screws onto the electrode 2l and' is loekec theireon by the jamb nut 3).
